Abstract
本发明公开了一种油气分离器，包括精分离模块和储油槽，其中，沿气体流动方向所述精分离模块的位置高于所述储油槽的位置，所述精分离模块与所述储油槽垂直布置，所述精分离模块的进气端朝向所述储油槽，所述精分离模块的出气端远离所述储油槽。由于气体流动方向与油液滴落方向相反，而且粗分离油气由底端向上流动，油液由精分离油气的入口端向下掉入储油槽内，即相当于储油槽布置在精分离模块之前，而不是布置在精分离模块气体出口端，这样单向阀的上下压差只来自粗分离的压阻，而粗分离压阻远小于精分离模块的压阻，这样可以保证在较小的储油情况下实现顺利回油。此外，本发明还公开了一种具有上述油气分离器的发动机及具有该发动机的汽车。
